      <h2 id="问题背景"><a href="#问题背景" class="headerlink" title="问题背景"></a>问题背景</h2><p>archlinux 是个可高度定制的 linux 发行版，在使用的过程中，需要反复测试很多软件包的功能，以达到自己想要的效果，效果不好的卸载，用得好的留下，但由于依赖是复杂的树状结构，时间长了，容易忘记自己测试过哪些包，以至于有些包只是临时安装的后来忘了卸载，随着积累容易导致在系统里留下大量不必要的包。</p>
<p>pacman 的功能之一是可以查询安装原因，安装原因有两种“单独指定安装”和“作为其他软件包的依赖关系安装”，也可以通过 pacman -Qdt 找出所有没必要的依赖包，pacman -Qe 可以列出所有自己显式指定安装过的包，还可以通过 pacman -Rscn 卸载某个软件来将其不必要的依赖也同时卸载。</p>
<p>虽然 pacman 功能强大，但依然没法满足以上需求，因为很多包都是自己指定安装，但是后来忘了自己只是临时测试这个包，测试过应当卸载，然而这类包显然留在系统中，这些包还不容易被找到，要是数量庞大，基本只能重装系统才能完全干净。</p>
<p>强迫症患者们当然希望自己的系统是干干净净，只有自己需要的包，没有其它任何垃圾包。</p>
<p>于是有了新的脚本需求………..</p>
